Galileo Galilei, "the father of science" and the man who has inspired many of the worlds greatest scientists. Galileo Portrait Galileo was a very energetic kid and loved to adventure and find new things, he was the oldest child and had a knack for playing the lute, which his father was famous for doing. He was born in February 15, 1564 son of Vincenzio, who was a famous musician back in the day and Giulia Galilei. Vincenzo wanted Galileo to have his own ideas and to be able to "raise his hand" and have questions about what he was being taught, but Galileo's father didn't exactly trust the schools when it hit in that topic so he home schooled him. It paid off to home school Galileo, because as he grew up he argued a lot on the act of defending his ideas, and he always encouraged others scientists to prove their ideas with experiments-- He had a nickname that was given to him because he argued so much (defending his ideas) it was, "The Wrangler" which meant he argued a ton. Galileo was smart and one of the best students in class at the university of Pisa, but his disagreements with Aristotle (a famous Greek philosopher, whom the Roman church admired and would approve with all his writings) lead the Roman Church to believe that he was a heretic. (someone who goes against the church or a system of beliefs) But was is it really wrong for him to express his ideas, especially when he had evidence? for them it was, but Galileo had another idea.
Moon Observations-- Galileo was having one of his usual sessions with the moon, glancing at it from far far away with his telescope to learn what he could about it. He noticed there were many hollow ares in the moon... he said these areas were craters. It didn't take Galileo long to find that the moon also had mountains, and that some of them were twice as big as the ones on earth! Galileo ClipArt --Galileo was proving that the moon did have flaws and thus his ideas went against Aristotle ( who believed the moon was a perfect ball and with no flaws) however, the Roman church believed and supported Aristotle's ideas and anyone who disagreed with them could be sentenced for heresy or even worse...die.

THRILLER MOON
( Galileo measured the shadow of the mountains, cast on the moon in order to know the mountains height.)
Jupiter and its moons--
Of all the hidden facts Galileo was discovering, Jupiter's moons was one of the greatest. He was gazing at Jupiter when all of the sudden four black dots appeared in jupiter's surface-- passing through in a pretty steady pace.At first, Galileo couldn't quite set his mind on what these dots were, but after studying them night after night he finally realized that these black dots were moons that orbited Jupiter! (like our moon orbits Earth.)
The names of the moons...
Galileo named the moons after Cosimo II de' Medici, otherwise known as the Grand Duke of Tuscany. They were called "The Cosimo Stars" but the Duke thought the name should honor him and his brothers so the name was changed to "The Medician Stars."
Simon Marius, a german astronomer named the moons after Zeus's lovers...Io, Ganymede, Europa, Callisto
He said he had discovered them at the sametime Galileo did and so he named them too.
Saturn Rings-- It was a dark and not so stormy night, when Galileo Galilei glanced through his telescope at what would be one the most puzzling discoveries of his time. Shining particularly bright on that night was a star, neighbored by two dimner stars. Galileo was simply amazed too see what he called a "triple bodied star." However, he became very puzzled when the dimmer stars or "handles"(as he called the neighboring stars of the central star)were no longer in sight. That question came to a conclusion when revisited by future astronomers and more advance technology. The name of this beautiful star is Saturn and it's the last planet in the solar system (well atleast back then it was.)

Sunspots on the sun-- There was this one "little" problem that Galileo would continuously face, as a scientist looking beyond Aristotle beliefs and that was that he, did not have the support of the Roman church.
Christopher Scheiner, was a Jesuit priest, physicist and astronomer who lived in Ingolstadt. When he came to visit Rome, he wrote a book about the sunspots called"Rosa Ursina sive Sol" that took the whole part of the research that was commenced on the sunspots. Christopher had seen the sunspots with numerous telescopes, looking at them for a year. At first glance they looked like dark mark imprinted on the sun's surface (thus sunspots) but Sheiner didn't think they were spot or"imperfections" on the sun, he believed they were tiny planets orbiting extremly close to the sun. Sheiner was convinced he was right however, Galileo knew he wasn't and so they got into a big wrangle. But since Galileo lacked the chuch's support and Sheiner did not, it seemed like Galileo were disagreeing with the church. As time crept along, the arguments only got worse and worse and Galileo was being deeply questioned of his faith to God.
Venus and it's phases-- It seemed like the more Galileo discovered world changing information, the more trouble he would head into with the Roman Church. It was in September of 1610, that Galileo moved to Florence and restarted his work with the marvelous telescope. With his telescope, he glanced high into the night sky and saw what would be his next greatest discovery.
Night after Night and it all came down too this...
Galileo had found that like the moon Venus has phases too. After studying and looking at Venus for several months, he could see clearly that it went from a bright red spot in the picth black space, to a diminute, almost nothing spot. That indicated that Venus, like wise the moon had a change in their looks... like a grow and shrink kind of look. There was a big time wise difference between the moon and Venus's phases and that is...Venus phases lasted a year and a half butThe moon's phases lasted a month.
